... which would be my preferred solution. I think new SoCs should have
some kind of:

        compatible = "commodore,c64ultra", "bosch,d_can";

in the DT anyhow to allow for SoC specific quirks/adjustments. And
custom raminit belongs to that IMO (see the ti routine getting more and
more specific).
